If you are in the restaurant business, you have seen extreme highs and lows. Amongst the highs, the lows seem to occur more frequently, resulting in loss of revenue. Don’t lock up the doors just yet. You can turn things around for your restaurant and your bank account.

Just as wine lists and food are typically offered on separate menus, CorkGuru is an iPad application dedicated to wine. Web-based, it also knows your restaurant’s inventory and removes depleted stocks from the list, making sure that guests only see what you can provide. Naturally, customers can peruse by categories of varietal, vineyard and price. They can also drill down to an individual wine’s tasting notes and potential food pairings. Sommeliers can accurately track sales and better tailor purchases to demand. Low-stock alerts prevent disappointments.
